We understand this fill was observed and tested during placement by others. The excavation penetrated the fill in the basement portion of the house. Foundation Recommendations: The foundation should conform to the master foundation plan for Journey Homes, LLC model 6- Unit Model provided by High Plains Engineering & Design, LLC, Project No. 15-5155, last dated January 5, 2015. Subsurface Drainage Recommendations: A subsurface perimeter drain is recommended around portions of the structure which will have habitable or storage space located below the finished ground surface. This includes crawlspace areas but not the walkout trench, if applicable. See Perimeter Drain section. Open Hole Observation: The recommendations provided in this report are based on the conditions exposed in the excavation at the time of our observation and information contained in the Subsurface Soils Investigation referenced above. These recommendations are based on accepted local engineering practice and arc intended for individuals familiar with local construction practices and standards. If exposure to the elements results in a change to these conditions at any point prior to foundation construction and/or backfllling the foundation, we recommend that RMG be contacted to re-evaluate the excavation to determine suitability of the recommendations contained herein. All previous recommendations included in the Subsurface Soil Investigation referenced above and not specifically addressed herein remain valid.
